Okay, I might have to use a 1000 points tournament list before I have time to assemble and paint anything new, so I'll have to go with what I've got:

Destroyer Lord w/sempiternal weave
C'tan Shard w/Time's Arrow, Gaze of Death
10 Warriors
10 Warriors
4 Destroyers
4 Destroyers

995 points

Yes, it doesn't look like much, but what I know of my opponents I'll probably be seeing Blood Angels, Grey Knights and Space Marines as my opponents, so plenty of Destroyers will give them something to be worried about. Tooled up C'tan should be able to hold its own in almost any combat while Destroyer Lord can hunt down vehicles. Sempiternal weave is just there to keep him covered against missile launchers.

My other models include: Monolith, 20 more Warriors, 2 more Destroyers, 1 more Destroyer Lord, 6 more Heavy Destroyers, 10 bases of Scarabs and 10 Flayed Ones.
